RF2347
• TDMA/CDMA/FM Cellular LNA
• Low Noise Transmit Driver Amplifier
• General Purpose Amplification
• Commercial and Consumer Systems
The RF2347 is a low noise amplifier with a very high
dynamic range designed for digital cellular applications at
900MHz. The device functions as an outstanding front
end low noise amplifier or power amplifier driver amplifier
in the transmit chain of digital subscriber units where low
transmit noise power is a concern. When used as an
LNA, the bias current can be set externally. When used
as a PA driver, the IC can operate directly from a single
cell Li-ion battery and includes a power down feature that
can be used to completely turn off the device. The IC is
featured in a standard miniature 8-lead plastic MSOP
package.
• Low Noise and High Intercept Point
• Power Down Control
• Single 2.5V to 6.0V Power Supply
• 150MHz to 2500MHz Operation
• Extremely Small MSOP-8 Package
